MacOS:如何解决"This app is damaged and can’t be opened. You should move it to the Trash"

Launch Terminal and then issue the following command:

xattr -cr /path/to/application.app

For example:

xattr -cr /Applications/Signal.app

The -c flag removes all attributes, whereas -r applies recursively for the entire targeted .app directory contents.
